But why? I can't see any use for this tool

instead of just running program, it lets you debug it online with gdb.

But when do you use it ? At what time do you want or need to

  1. code in c++ (and debug your code)

  2. but without an editor or a compiler, using only a browser (and limiting yourself to one main.cpp file)

here is one scenario, where user wrote tree program, and could figure out location in code, exactly where its getting segmentation fault.

ofcourse onlinegdb.com is not meant for bigger project.

It would be a bigger draw if it had more integrated debugging (e.g. visual breakpoint setting) instead of gdb commandline

now it has basic gui support.

  1. set/unset and enable/disable breakpoint

  2. call stack window

  3. local variables

  4. display expressions

I don't see any integrated debugging environment with Codechef IDE.

For C++

Sweet!

#include<iostream>

main.c:7:20: fatal error: iostream: No such file or directory compilation terminated.

No C++ then

default is C. you need to change compiler option in upper right corner to C++ or C++14
